Bethesda has announced that the first proper DLC expansion for The Evil Within, titled "The Assignment", is now available to download on PC. It's the first of two big DLC packs for the game and will be followed up by "The Consequence" later this Spring (no, it's not Spring yet, it's still Winter... we think).
"In The Evil Within: The Assignment and The Evil Within: The Consequence, players take on the role of detective Juli Kidman, Sebastian Castellanos’ mysterious partner, in a concurrent story that looks to answer some of the questions surrounding her whereabouts during The Evil Within. Along the way she will encounter disturbing new enemies, discover new mysteries, and uncover new horrors. The Assignment and The Consequence give fans of The Evil Within the perfect opportunity to discover detective Kidman’s hidden motivations and her mysterious connection to Mobius, the shadowy group thought to be behind the gruesome events of The Evil Within."
The Assignment is either available individually at £6.99 or as part of Evil Within's Season Pass which I can't remember if I bought or not. We'll have a review up in due course, meaning "as soon as Steam stops screwing around and actually downloads the damn thing".
